• Device Registers—Test patterns are written, read, and verified through the adapter's device registers
to check proper functionality.
• FIFO—This option writes test bit patterns to the adapter's FIFO buffers to check the FIFOs proper
functionality.
• EEPROM—This option tests both the readability of the EEPROM as well as the integrity of the data
stored in the EEPROM. It reads EEPROM and calculates the checksum. This checksum is then
compared to the checksum stored in the EEPROM. If the values are not identical, the test reports
failure.
• Interrupt—This option tests the adapter's ability to generate an interrupt and have it propagated
through the system to the Programmable Interrupt Controller (PIC). The test triggers an interrupt by
setting the interrupt cause register and then verifies that an interrupt has been triggered. On EFI,
interrupts are not supported, Therefore, this test sets the interrupt cause register and reads the
interrupt set register, which verifies the card internally registered an interrupt.
• Loopback Tests—These options are internal loopback tests. These tests set the adapter in the
appropriate loopback mode and send packets back through the adapter's receive circuitry and
logic.
• Link—This option checks to see whether or not the adapter has link.
• Network Test—This option tests network communication. It looks for a responder and then sends
packets. If no responder is found, then the test reports failure. If packets are received back from the
responder, the test reports success.
Displaying Diagnostic Log
The Display Diagnostic Log option allows you to view a detailed report of the tests you just ran. When
Diagnostic Log is enabled, test results are recorded in a log file named DIAGS.LOG. If it does not already
exist, the test utility creates it. If it already exists, new data is appended to it. The DISPLAY DIAGNOSTIC
LOG command displays the contents of the log file for your convenience. Each entry in the log file is time
stamped. The test run banner identifies the tested adapter according to its bus slot address.
Accessing the networking submenu
The networking submenu allows you to setup the adapter as a responder and to detect a spanning tree on
the network.
• Setting up as a responder—This allows the user to set up the adapter as a responder so another
system can perform the continuous network test. Selecting this option displays the transmit/receive
screen. This test will fail if the adapter does not have link. Although you can use a variety of
adapters as responders, and either connect directly (with a crossover cable) or through a switch,
ideal results are obtained with a same-type adapter.
When you press the Esc key, the responder operation is cancelled and control is immediately
returned to the Test Adapter menu.
• Detecting spanning tree—This allows the user to detect if a spanning tree is used on the network.
HP NC-Series Broadcom adapter diagnostics
Overview
The diagnostic software lets you test adapters to see if there are any problems with the adapter hardware,
cabling, or network connections. HP recommends that you run diagnostics every time you install an
adapter.
